Mine used to freeze up with in minutes down here in hot/humid Florida until I adjusted the sensor to be closer to the evaporator coil that was freezing up. I believe it was 1/8th to 1/4" off of the coil. I adjusted it to be more like a 1/16th of an inch off the coil, not touching though, and have not had a problem in over 4 years.

I have a small snag, Any Idea where this black plug goes? The system seems to work without it but I have no idea where it goes...

I think that connector may go to the temperature actuator. Just in case you did not get these instructions.

So my '09 Elise has recently begun displaying the same problem. Works fine for 10-15 minutes, then drop in airflow and increase in temperature. Shut off AX for 20-30 seconds, air flow increases substantially, turn on AC nice and cold. Given that it's a 2009, I'm assuming I have the newer thermostat, so perhaps relocating the sensor is the next thing to try, if I confirm thermostat is good (I guess it could be the electronic version, but have gone bad).

Your car has the upgraded electronic thermostat and should not exhibit the symptoms you describe.. I would suggest, firstly, to make sure the sensor (thermistor) is positioned as per the instructions I posted above. Then I would check all of the connections and if all is OK then maybe you do have a defective unit.

My January 08 build 08 Exige s240's AC was exibiting the lack of airflow symptoms. Even though I kept complaining to the 3 different dealers (two of them no longer exist) they swore up and down that . (Probably because they know it's a clam off repair (for the Exige) and lotus obviously doesn't want to foot the bill.) I tried to get them to install a new AC thermostat but luck was on their side and my warranty expired. Since owning the car i've realized that lotus uses old parts even when there are TSB's or recalls to install new parts months to years before. Anyway, while upgrading the oil cooler lines I took the opportunity to replace the AC thermostat. I do indeed have an electronic thermostat and the probe was installed in the correct orientation but the part numbers (65265) did not match the new part. There were also a few slight differences in the connectors as well.
Finally, the AC works great now and consistently flows cold air! I no longer have to turn off the AC every 15 minutes to let the condenser thaw out.

Glad it is finally working fine for you.

Does ANYONE know if the Electronic Sensor is compatible with the 2002 Lotus.
Latest shape - Rover Motor. It seems to look the same as your pics above.

Thanks in advance.

Thanks HocusLotus for pictures and commentary. I never would have been able to do the update without them. Took longer than 1.5 hours but much of that was because of Tony Wa's coolant modification.

2005 Elise was updated without taking Clam Off.
